Sessions

You can manage sessions in the following scenarios:

If the number of sessions of an instance has reached the upper limit and the instance cannot be logged in to any longer, you can view and kill unnecessary sessions using the emergency channel function.
You can view history logs to learn details of the kill operations that you performed using the emergency channel function.

Killing a session may cause instance or service exceptions.

If it can be logged in to through DAS, log in to your instance on the DAS console and enter the commands to kill the sessions in question from there.
Use this function in urgent conditions. All your kill operations will be logged.
